the Purchaser may reach in and get the 011D; broken away of the mixingvalve employed in the 45 I Referring now to the said drawings, thereference numeral l designates the novel automatic drink vending machineof this invention ,as a whole. This machine comprises a cabinet 2 havingfront and back walls 3 and 4, side walls 5 and 6- and relatively narrowwalls I and 8 interconmeeting the front and side walls. Cabinet 2 has ahollow translucent or transparent advertising device 9 at the topthereof within which is preferably contained a suitable electric lightand on the exterior walls of which are depicted suitable advertisingmatter H. The front, side and interconnecting walls of the cabinet 2 areeach provided with a compartment door I2, each of which doors isdisposed substantially centrally 01' its respective wall.

Above each door is depicted the name of a respective drink, therebydesignating the type of drink served through such door. Slightly to theright of each door I2 is provided a coin receiving aperture l3 of a sizeconforming to a particular denomination of coin, for example, a fivecent piece. Further to the right of each door I2 is provided a used cupreceiving aperture M of a shape adapted to receive a cup when the sameis held in a vertical position. The used cup apertures l4 aresymmetrically arranged with respect to the doors l2, thereby causing thecabinet 2 to have a neat and attractive appearance. In the form of theinvention shown in the drawings, the cabinet is illustrated as havingfive cup compartment doors, adapting the same to serve five diiferentdrinks, but it is to be understood that this cabinet may have a lesseror even greater number of such doors, if desired. Also, two cabinets maybe arranged back to back when desired, thereby presenting a handsomeappearance and enabling the sale of ten different carbonated drinks.

Substantially centrally disposed within the interior of the cabinet 2 isa casing I 5 (see Fig. 2) containing an electric refrigerator consistingof a refrigerator unit i6 (see Fig. 9) connected by piping I! to thecooling jacket l9 of a closed carbonated water cooler container i8. Anexpansion valve 20 is provided in piping H where this piping joins thecooling jacket 19 so that refrigerant expanding within jacket l9 willeffect the cooling of the carbonated water 2| contained within watercontainer l9. Carbonated water under pressure is supplied from apressure tank 22, situated in the lower part of cabinet 2, by means ofpiping 23 to container l8, within which container the carbonated wateris cooled to a relatively low temperature by the refrigerating action ofthe refrigerator unit.

Container I8 is provided with outlet piping 24 to the upper end of whichis connected a plurality of branch pipes 25. The branch pipes 25 areadapted to conduct the cooled carbonated water to mixing valves 26, fiveoi which valves are illustrated in the drawings, corresponding to thenumber of diifering drinks dispensed by the machine. Valves 43 areincluded in pipes 25 adjacent the respective mixing valves 26 in orderto shut oil the supply of cooled carbonated water to these valves,

- when desired. A plurality of removable jars 21 are contained withinthe upper part of cabinet 2, which jarsvare adapted to contain thevarious flavors or syrups dispensed by the machine. Jars 21 are mountedin inverted position with their necks 28 projecting downwardly intohoppers 29, which hoppers serve" to support the jars'and areillustrated'as having gaskets 30 for sealing the joint between the topsof the jars and the hoppers. Hoppers 29 aresconnected by pipes 41 to themixing valves 26. The lower portions of hoppers 29 are illustrated ashaving valves 32 which permit the shutting ofl of the supply of syrupwhen desired.

One of the mixing valves 26 is shown in detail in Figs. 10 and 11 andconsists of a casing having a cylindrical valve recess 33 therein.within which is slidably contained a piston 34 that has a piston rod 35extending therefrom. A coil compression spring 36 contained withinrecess 33 bears against the piston 34 and urges the free end of pistonrod 35 against a. plunger 31 that is reciprocally mounted within acylindrical recess 38 provided in the casing of valve 26. An annularstop shoulder 39 is provided within valve cylinder 33 for limiting themotion of piston 34 under the action of spring 36. With piston 34abutting stopshoulder 39, the said piston serves to close a port 46 inthe valve casing, which port communicates, by means of a passage 42,with one of the pipes 25 leading to the outlet piping 24.

A camming lever 44 is pivotally mounted upon a projection 45 formed onthe casing of valve 26, which camming lever has. cams 46 formed thereon.One of the cams 46 is adapted, upon the turning of lever 44, downwardly,to effect the inward movement of plunger 31 and piston rod 35, therebycausing piston 34 to compress spring 36 and effect the opening of port40 so that in use, carbonated water under pressure may flow from thepipe 25 through passage 42, port 40, and into cylindrical recess 33. Thecylindrical recess 33 is provided with a relatively small aperture 49,which communicates through a short tube 49 to the interior of a smallmixing chamber 50 formed in the casing of valve 26. Thus, the carbonatedwater under pressure within cylindrical recess 33 will flow throughaperture 48 and tube 49 into the mixing chamber 50 when plunger 31 isdepressed by the action of camming 4 .a second cylindrical recess 5|which extends parallel to the recess 33. Recess 5i has a piston 34movable therein which is similar to piston-34. The piston rod 35 ofpiston 34 is urged against a plunger 31 by the action of the coil spring36'. With piston 34' in engagement with an annular shoulder 39' underthe action of spring 36', the said piston serves to close a port 52which communicates, by means of a short tube 53, to the interior of thesmall mixing chamber50. Pipe 3| leading to one of the jars 21 is adaptedto convey syrup into an aperture 54 which communicates with thecylindrical recess 5|. When plunger 31' is pressed inwardly by cam 46 ofcamming lever 44, piston 34 uncovers the port 39' so that syrup flowingthrough pipe 3|, passage 54 and cylindrical recess 5|, will enter port52 and pass through tube 53 into the small mixing chamber 50 to be thereintermixed with the pre-cooled carbonated water. From the small mixingchamber 50, the intermixed carbonated water and syrup will flow into alarge tubular mixing chamber 55 which extends vertically downwardly fromvalve 26. A spout 56 is attached to the lower end of mixing chamber 55and serves to conduct the intermixed syrup and carbonated water to adrinking cup aswill further appear.

The outer free end of camming lever 44 is pivotally connected to theupper end of a depending link 51 which has its lower end pivotallyconnected, as by a pin 58, to the upper end of an armature 58 that isadapted to telescope within a solenoid 80. Armature 58 is normally heldin its upper and withdrawn position with respect to the solenoid 68 bymeans of a coil,

As especially shown in Figs. 3 to 5, the bracket 63 has a bell cranklever 64 pivotally mounted thereon as by means of a pivotal pin 13. Onearm of bell crank lever 64 depends downwardly and is pivotallyconnected, as by a pivotal screw 85, to the operating arm 66 of a cupdispenser 61. The cup dispenser 8'1 is old and of well knownconstruction and is thought to require no detailed description. Thepreferably waxed paper cups 68 of the dispenser 61 are confined in avertical position, as by vertical rods 68, extending upwardly from themain portion of the cup dispenser. Each time the operating lever 66 isactuated, a cup 68 will be dropped vertically downwardly from thisdispenser and past the discharge mouth of spout 56. The other arm ofbell crank lever 84 is inclined upwardly somewhat to the horizontal, andhas the upper end of a depending tension spring 18 connected to its freeend portion. The lower end of spring 78 is connected to a screw H whichis threaded into the depending link 51.

The tension ofspring 18 tends to turn bell crank lever 64 in acounterclockwise direction, as viewed in Fig. 5, thereby tending tocause an operating movement of operating arm 68 of the cup dispenser 81.Movement of bell crank lever 64 under the action of tension spring 18 isnormally prevented, however, by a roller stop 12 that is carried by thedepending link 51 and engages the underside of the upwardly inclined armof bell crank lever 88. When depending link 51 is pulled downwardly,however, as when solenoid 88 is energized, the roller stop 12 will movedownwardly'as will also pin 1|, so that spring 10 will cause theactuation of bell crank lever 64, resulting in the operation of the cupdispenser 61. The cup dispenser 5'! thus acts to discharge a cup whichfalls downwardly past the drink discharge mouth of spout 58 and passesinto the hollow interior of a cup embracing bracket 15. The cup thencomes to rest in an upright position with its bottom resting upon atipping platform or pan 14 and with its sides embraced by bracket '15.

The cup embracing bracket;v is of c-shape, as viewed in plan, and isopen at the front so that a cup can be readily withdrawn therefrom,

although this bracket I5 serves to maintain the cup in an uprightposition upon the tipping platformor pan 14 until the user removes thesame therefrom. The cup embracing'bracket 15 is supported at itsrearupon the upper end portion of a strut 16 which extends downwardly andthrough an aperture provided in the platform 14 and has a forwardly-directed flange at its lower end which is secured to a beam 11.

form or pan 14 is supported upon the lower portion of strut I8, as bymeans of a transversely extending angle bar I8 which is secured to theunder-surface of the tipping platform and to the strut 16. The strut 16thus serves to support the tipping platform 14 upon beam 11. Beam I1 isformed with transverse extensions 80 at its sides, which extensions havedown-turned ears 80' at their ends, which ears are pivotally mountedupon a transversely extending pivotal rod 8|. Pivotal rod 8| has itsends supported by upwardly directed ears 83 formed at the sides of ahorizontal bracket 82 which is attached to the easing i5.

Owing to the pivotal mounting of the beam 11 upon pivotal rod 8| carriedby bracket 82, this beam and the platform 14 are adapted to turnsomewhat about a horizontal axis. The beam 11 is provided with stopscrews 85 and 85' near its ends, which screws, by engaging the bracket82, serve to limit the turning or tipping movement of the beam TI and ofthe platform or pan 14. The beam 11 carries an adjustable weight 86which may be nicely adjusted so that the tipping platform H willnormally remain in a somewhat forwardly and downwardly inclinedposition, (see especially Figs. 4 to 6) with the stop screw 85' inengagement with the bracket 82. The weight 86 is so adjusted, however,that when a cup 68, resting upon the tipping platform 14, receives thedesired quantity of drinking fluid. the weight of the cup and itscontents will serve to tip theplatform 14 forwardly somewhat byoverbalancing. the weight 88, thereby moving the screw 85 intoengagement with bracket 82, as illustrated in Fig. 7.

The tipping platform or pan H is provided with flanges at its sides andwith a V-shaped flange 81, which flanges project upwardly from theupper-surface of platform 14 and serve to conduct any liquid spilt uponthis platform to a spout 88 formed in the forward portion thereof. Owingto the inclination of the platform or pan l4, liquid spilt thereon willflow naturally to spout 88 and will be discharged from this. spout intothe flared upper end portion of a depending waste pipe 89, which servesto convey such spilt liquid downwardly and into a sump or pan 88positioned at the bottom of the cabinet.

A mercury bulb switch 9| is mounted upon a clip 92 that is secured tothe upper surface of platform 14 at the rear of panel 18. Mercury bulbswitch 8| is so positioned with respect to the cup platform 14 that whenthis platform is in its normal slightly inclined position, i. c. withthe stop screw 85' in engagement with bracket 82, the mercury withinthis bulb switch will engage the terminals of the switch so that, ineffect,

this switch is closed. A lead 83 is connected to.

one terminal of mercury bulb switch 8| and a second lead 84 is connectedto the other terminal of this mercury bulb switch. Lead 84 extends toone terminal of the solenoid 60, the other terminal of which solenoid isconnected by a lead 85 to one lead 86 of a current supply line having asecond lead 81.

A second mercury bulb switch 88 is mounted upon a clip 88 that is alsosecured to the upper surface of platform I4 at the rear of panel 18.Mercury bulb switch 88 is so positioned with respect to the cup platform14, that when this platform is in its normal slightly inclined position,i. e. with the stop screw 85' in engagement with bracket 82, the mercurywithin thisbulb switch is out of engagement with the terminals of thlsswitch so that, in effect, this switch is open. When the platform I4 istipped forwardly, however, under the weight of a filled cup 68, themercury within bulb switch 98 will shift so as to complete a circuitacross the terminals of this switch, as especially shown in Fig. 7,whereas the circuit through bulb switch 9i will be broken, owing to theflowing of the mercury away from the terminals of switch 9| when theplatform tips forwardly.

One terminal of mercury bulb switch 98 is connected bya lead I00 to thesupply lead 91. The other terminal of switch 98 is connected by a leadIM to one terminal of a door operating solenoid I02, the other terminalof which solenoid is connected by a lead I03 to the supply lead 98. Thecore I05 of door operating solenoid I02 is mounted upon a bracket I04that is fixed to the casing I5. An armature I06 is adapted to telescopewithin the hollow interior of solenoid I02 and extends downwardly fromthis solenoid.

A depending racki0! is pivotally connected at its upper end, as by a pinI 08, to the armature I06 and has its lower end portion slidably guidedina slide bearing projection I09 formed on the bracket I04. A dependingcircular rod IIO has its upper end secured to the lower end of rack I01and the lower end portion of this rod I I0 projects downwardly throughthe top of an air check cylinder III. The lower end of depending rod IIOhas a check piston II2- fixed thereto for reciprocation within checkcylinder III. The uper and lower portions of check cylinder III areprovided with relatively small apertures I I3 and H3 which may be madeadjustable as to size, if desired, in a manner well known to thoseskilled in the art. Apertures I I3 and H3 serve to check the movement ofcheck piston I I2 within cylinder I I I and hence serve to checkreciprocating movements of rack I0I in use. The teeth of rack I0! meshwith a gear H4 that is fixed upon a forwardly extending shaft H5. Therear end portion of shaft H5 is turnably mounted upon a bearing providedin the bracket I04, whereas the front end portion of this shaft ismounted in a bearing provided in an extension II6 of the bracket I04.

A sheave'.II'I is fixed upon the forward end portion of shaft I I5 andhas a chain I I8 passing thereover. One end of the chain H8 is fixed tothe periphery of sheave H1 and the other end of this chain is attachedto a bracket II9 that is secured to the upper portion of a cupcompartment door I2. The door I2 is adapted to slide upwardly in movingfrom closed to open position and is guided in its movement by verticalguides I25 attached to the inner wall surface of cabinet 2. Door I2 ispreferably transparent and may be made, for example, of any suitablecellulosic material. A knob or handle I20 is shown attached to the lowercentral portion of the door I2, which handle projects outwardly of thecabinet 2. A transverse bar, such as an angle bar, extends across thelower rear portion of door I2 and has a horizontal flange I 2Iprojecting rearwardly of this door, which flange is adapted to cooperatewith pivoted latches I22 which are pivotally these latches in acounterclockwise direction so that they will engage flange I2I andthereby serve to retain the door I2 in closed and locked condition.Latches I22 have rearwardly directed releasing projections I26 which areadapted to cooperate with a transversly extending bar I2'I carried bythe forward portion of the cup platform I4. With the door I2 in closedposition, as shown in Fig. 6-, and with the cup platform I4 in itsnormal position (i. e. with stop screw 85 engaging bracket 82) thelatches I 22', by engaging the flange I 2 I, will serve to lock the doorin closed position, while the releasing projections I26 are positionedimmediately below the under surface of bar I21.

After a cup 68 has been filled with a predetermined quantity of drink,however, causing platform I4 to tip forwardly, as shown in Fig. '7, thetransverse bar I2'I will act to move the releasing projections I26downwardly, thereby turning latches I22 rearwardly about their pivotalconnections with the bracket 82 and effecting the unlocking of the doorI2. The forward tipping of the platform I4 also completes a circuitthrough mercury bulb switch 98, thereby effecting the energization ofdoor operating solenoid I02 (see especially Fig. 8) and causing upwardmovement of armature I06, resulting in the turning of gear H4 and sheaveIII, to thereby raise door I2 to open position and permitting thepurchaser to insert his hand, as shown in Fig. '7, and remove the filledcup.

The coin control mechanism consists of a depending flattened conveyingtube I29 which extends downwardly and rearwardly from the coin receivingaperture I3 (see especially Figs. 3 to 7) The conveying tube I29 has aninternal cross section substantially conforming to that of thedenomination of coin used, i. e. when the coin is viewed edgeways, andthis tube serves to convey the coins to the forward end portion of apivoted beam I30. The coins are delivered so that their edges strike thebeam I30, the faces of the coin extending transversely of the beam asshown in dot and dash lines in Fig. 13. Beam I30 is pivotally supportedsubstantially midway of its lengthas upon a pivotal pin I3I carried by abracket I32 that is fixed to the casing I5. As especially shown in Fig.13, the forward portion of beam I30 is provided with a slot I33immediately underlying .the discharge end of tube I29. Slot I33 is ofslightly lesser width than the diameter of a genuine coin intended to beused in the machine, so that fictitious coins of smaller diameter thangenuine coins will fall through slot I33 and will not serve to turn thebeam I30. A coin box I40 is provided below the forward end of beam I30for receiving coins dr0pped.from this beam.

A genuine coin will not fall through the slot I33, but the edges of sucha coin will strike the beam I30 at the sides of slot I33 and move theforward end of the same downwardly somewhat until this end of the beamengages the upper-"surface of the pivoted armature I34 of a holding coilI35. Armature I34 is pivoted at I39 upon the core frame of holding coilI35. A tension spring I43 pulls upon one end of armature I34 and urgesthe other end thereof upwardly and toward the under surface of beam I30.A suitable stop I44 serves to limit the upward turning movement ofarmature I34, thereby serving to hold this armature somewhat spaced frombeam I30. The beam I30 is nicely balanced so that'the weight of agenuine coin will cause this beam to turn about the pivotal pin I3Iuntil the turning motion of the beam is stopped bythe same contactingwith beam I is preferably provided with an adjustable weight I 30 sothat the same may be nicely balanced.

A mercury bulb switch I31 iscarried by a clip I30 which is attached tothe under surface of beam I30. One terminal of mercury bulb switch I31is connected to lead 93 while the other termi nal of switch I31 isconnected by a lead I (see especially Fig. 8) to supply line lead 91.The mercury bulb switch I31 is so held by clip I38 that prior to theengagement of beam I30 by a coin, the mercury of this switch does notengage the terminals of the switch as shown in Figs. 4 and 5.

In use, the tipping of the beam I30, caused by the insertion of theproper coin into coin aperture I3, causes the mercury in bulb switch I31to engage the terminals of this switch, thereby completing a circuit forholding coil I35. This circuit (see Fig. 8) is from supply lead 91, byway of lead I4I through switch I31, lead 03, switch 9|, lead 94, leadI42, holding coil I35, lead I43 and lead 95 to supply lead 96. Thus, assoon as a coin strikes the beam I30 causing the same to tip downwardlyuntil stopp d by pivoted armature I34, a circuit is completed forholding coil I which immediately acts to draw armature I34 down to thecore of this coil and causing beam I30 to tip still lower and effect thecomplete dislodgment of the coin from tube I29, which coin falls intobox I40, as especially illustrated .in Fig. 6. The beam I30 is shown ashaving an iron piece I46 on the under surface thereof, which piece isattracted by the magnetism of the holding coil so that the beam I30 isheld in its down tilted position shown in Fig. 6 after the coin hasdropped from this beam.

The closing of switch I31 also completed a circuit for the solenoid 60.As especially shown in Fig. 8, this circuit extends from supply lead 91,through lead I4I, switch I31, lead 93, switch 9i, lead 94, solenoid 60,lead 95 to supply lead 96. The energization of solenoid 00 causesdownward movementof armature 59 against the tension of spring SI. Asarmature 59 commences to move downwardly, the link 51 also movesdownwardly so that the tension of'spring 10 causes movement of bellcrank lever 64 and effects an operation of cup dispenser 81, resultingin the discharge of a cup from this dispenser 61, which cup fallsdownwardly and is received upon the cup platform 14. Continued downwardmovement of armature 50, causes the cams of camming lever 44 to pressplungers 31 and 31' of mixing valve 20 inwardly. This action of thecamming lever causes intermixed carbonated water and syrup to flow fromvalve 20 downwardly through mixing chamber 65 and through spout into thecup 68.

The mixed drink continues to flow into cup 68 until this cup issubstantially filled, whereupon the weight of this cup and its contetscausescup platform 14 to tip forwardly until stop screw 05 engagesbracket 02. The forward tipping of platform 14 causes the opening ofswitch SI and effects the deenergization of solenoid as well as thedeenergization of holding coil I35. The deenergization of solenoid 60permits tension spring 6| to immediately return armature 59 to its upperposition, thereby turning camming lever 44 upwardly to effect theshutting off of the supply of mixed drink through valve 20. At the sametime, bell crank lever 64 is returned to its initial position readyfor-another'operation of the cup dispenser. The deenergization of theholding coil I35 permits beam I30 to swing up wardly into its initialposition, i. e. in abutting relation to the lower end of coin conveyingtube I29.

The forward tipping of cup platform 14, due to the weight of the filledcup, also efiected the unlatching of latches I22 and likewise caused theclosing of switch 08, resulting in the energization of door operatingsolenoid I02, which effects the raising of the door I2 so that thepurchaser may insert his hand, as shown in Fig. 7, and remove the filledcup 08. When the purchaser removes the cup 08, the forward portion ofcup platform 14 will turn or tip upwardly owing to the presence ofweight 80, thereby opening switch 88 and reclosing switch SI. Theopening of switch 98 permits the door I2 to descend by gravity, the dashpot III serving to suitably check the downward movement of the door.

When the door has reached its lowermost position, the latches I22 snapover the angle bar I2I, thereby locking the door in closed position andthe apparatus is again in condition for another operation. The purchaserwhen through with his cup may insert the same in an upright positionthrough one of the cup apertures I4 provided in the machine, andsuch cupwill be conducted downwardly, while still in a vertical position, by avertical guide tube I48 (see Figs. 3 and 5). The cup will thus fall inan upright position upon pan 90 and subsequently deposited cups willstack up upon this first cup, thereby forming a compacted mass of usedcups which will require relatively little space within cabi-' net 2.

Since the machine of this invention is provided with five independentlyoperating drink dispensing mechanisms, two or more differing drinks maybe dispensed simultaneously so that a number of persons may have accesssimultaneously to the machine, thereby enabling the machine to have alarge output of the various drinks. Owing to the use of the coolingjacket I9 surrounding the carbonated water reservoir 2 I, the drinks aresupplied in a cold condition suchas would be obtained from an ordinarysoda fountain. Applicant, by using the cooling jacket I8, alsoeliminates the multiplicity of complicated and expensive cooling collsas heretofore used in devices of this character.

It will be apparent that the door operating solenoid I02 and associatedmechanism may be omitted, if desired, thereby simplifying the machine,in which event each door I2 will be opened by the purchaser graspinghandle I20 and manually raising the door. After removing the filled cupof beverage, the purchaser will release the door handle, whereupon thedoor will close by gravity and will be locked in closed position by thelatches I22.

As many changes could be made in the above construction and manyapparently widely differ ent embodiments of this invention could be madewithout departing from the scope thereof, as defined by the followingclaims, it is intended that all matter contained in the abovedescription or shown in the accompanying drawings shall be interpretedas illustrative and not in a limiting sense.
